The recent Windows 11 update caused the CPU to heat up significantly, and I considered undervolting as a solution. However, I'm unsure about the optimal approach for these advanced CPUs, especially with voltage restrictions in Asus Armoury Crate. Setting PBO to -15 in BIOS is a conservative choice. Interestingly, the laptop shown in the video looks identical to mine. Regarding Ryzen 9 undervolting, what are the typical recommendations or best practices?

You can adjust the temporary limits as needed. Otherwise, I’d lower it further for CO... -30. Stability concerns suggest reducing it. PBO might reach up to positive 200 too. Beyond these bounds, those settings help boost performance while cutting power and heat.

This CPU seems to handle performance well, but I'm concerned about stability. The PBO -30 setting doesn't seem reliable anymore. On my 5800X3D it worked fine with no issues, but some games keep crashing even at lower temperatures. Maybe the power or temperature limits are better suited for this setup. The R9 and CPU differ significantly, so I'm not sure what's causing the problems.
